New NPP
Just installed the NPP on my '05/A4. Have to say i wasn't expecting it to be so "impressive" as for as sound level. 
Has a nice/deeper tone than the Corsa sports. And it really cackles @ WOT. I can't sneek around anymore.
Ed, i need my NPP in a box..
What a great invention. Can't wait to get it on there.

The bass note witht he Z06 and the NPP controller is deeper bass note and witht he cam lope its sick sounding. Almost like I have a powerful fast car.

Explain NPP
Would someone please explain what's involved in this exhaust mod. I understand the obvious w/ pipes & mufflers, but this does involve a switching/actuating system, what's involved. This is the system that would allow for quiet cruising or wide open on the fly, right? While I'm asking, anyone have ballpark on parts cost.

Just installed the NPP in a Box last nite. What a cool mod. (Thanks Ed
) just for comparison - closed/mild is a little louder than stock and a little deeper in sound. Open/wild is, well WILD... Deeper than Corsa's, and did i mention WILD? You also get to choose what mode it starts in, open or closed.
10min. install for the NPP in a box, very sweet.
Hey Spin, you are so right about how mean it sounds open with the cam @ idle, and @ WOT... have your tissues ready to keep it off the seats...
